7 / 20 is the same as 7 divided by 20

Simply put that in your calculator to get 0.35

Hope this helps!

\frac{7}{20} =  \frac{7 \times 5}{20 \times 5} = \frac{35}{100} = 0.35

Hope that makes more sense to you as to why 7/20 = 0.35

Lisa [10]

Answer:

1 2/6 is the correct answer

Step-by-step explanation:

in 2 1/6 + -5/6 what you do is you can turn the plus sign into a minus sign and  make -5/6 5/6 so now the problem is 2 1/6 - 5/6 and the awnser to that is 1 2/6

Find in degrees.<br> 11<br> B<br> 6<br> [?]°<br> Round to the nearest hundredth.<br> Enter
avanturin [10]

Answer:

\beta  = 28.610

Step-by-step explanation:

in this case we have a right angled triangle, whenever you see this triangle think of the TRIG RATIOS * sin, cos & tan* but if it was another triangle besides right angled triangle you use SINE RULE OR COSINE RULE

SOLUTION

\tan( \beta )  =  \frac{opposite}{adjecent}  \\  \tan( \beta )  =  \frac{6}{11}  \\  \beta  =  tan(inverse)( \frac{6}{11} ) \\  \beta  = 28.61045

If 10^x equals 0.1 percent of 10^y, where x and y are integers, which of the following must be true?
andrew-mc [135]
10^x=0.1 \% \times 10^y \\ \\&#10;10^x=\frac{0.1}{100} \times 10^y \\ \\&#10;10^x=\frac{1}{1000} \times 10^y \\ \\&#10;10^x=\frac{10^y}{10^3} \\ \\&#10;10^x=10^{y-3} \\ \\&#10;\log_{10} 10^x=\log_{10} 10^{y-3} \\ \\&#10;x=y-3 \\ \\&#10;y=x+3

The answer is B.

Please explain how to solve this problem

Answer:

  • 100 pounds Earl Grey
  • 300 pounds Orange Pekoe

Step-by-step explanation:

Let x represent the number of pounds of Earl Gray tea in the mix. Then the total cost of the mix is ...

  6x +4(400-x)=4.50(400)

  2x +1600 = 1800 . . . . . . . simplify

  2x = 200 . . . . . . . . . . . subtract 1600

  x = 100 . . . . . . . . . . . divide by 2. Pounds of Earl Grey

  (400 -x) = 300 . . . . . Pounds of Orange Pekoe

The blend should have 100 pounds of Earl Grey and 300 pounds of Orange Pekoe.

_____

<em>Additional comment</em>

It is easy to show that the relationship between the quantities of high-cost (H) and low-cost (L) items in the mix (M) is ...

  fraction of mix that is H is (M -L)/(H -L)

Here, we have H=6, L=4, M=4.5, so the fraction of the mix that is Earl Grey is ...

  (4.5 -4)/(6 -4) = 0.5/2 = 0.25

There are 400 pounds of mix, so 0.25(400) = 100 pounds is Earl Grey.

The solution above is essentially 2-step, so using this relation doesn't necessarily save any steps. It just makes it possible to solve the problem in your head.
